Passenger-airbag installation module

Abstract

A module for installing a passenger airbag, having a trough-like housing (1). The housing essentially comprises a U-shaped base (2) and two essentially flat ends (3). The module also includes a gas generator (4) and a gas sack (5). The gas sack is folded into the housing over the gas generator, One marginal section (6) of the gas sack (5) is wrapped outward around the edge (7) of the housing (1) all the way around. The marginal section (6) is looped along the base (2) around connecting rods (8). The connecting rods secure the ends (3) to the base (2) and extend within a groove-like inward-opening depression (9) in the base (2). A continuous tensioning band (10) attaches the marginal section (6) of the gas sack (5) to the outside of the housing (1) between the edge (7) of the housing and the connecting rods (8), constituting a force-application attachment.

We claim: 
     
       1. Module for installing a passenger airbag, having a trough-like housing (1) essentially comprising a U-shaped base (2) and two essentially flat ends (3), with a gas generator (4) and with a gas sack (5) folded into the housing over the gas generator, characterized in that one marginal section (6) of the gas sack (5) is wrapped outward around the edge (7) of the housing (1) all the way around, in that the marginal section (6) is looped along the base (2) around connecting rods (8) that secure the ends (3) to the base (2) and extend within a groove-like inward-opening depression (9) in the base (2), and by a continuous tensioning band (10) that attaches the marginal section (6) of the gas sack (5) to the outside of the housing (1) between the edge (7) of the housing and the connecting rods (8), constituting a force-application attachment. 
     
     
       2. Module as in claim 1, characterized in that the housing (1) has a shallow depression (11) as wide as the tensioning band (10) extending all the way around it and constituting an interlocking attachment of the marginal section (6) of the gas sack (7) to the housing. 
     
     
       3. Module as in claim 1, characterized in that the gas sack has a protective cover (12), one marginal section of which can be secured to the housing (1) along with the marginal section (6) of the gas sack (5) by the tensioning band (10). 
     
     
       4. Module as in claim 1, characterized in that one marginal section (13) of a lid (14) can be secured to the housing by the tensioning band (10) along with the marginal section (6) of the gas sack (5). 
     
     
       5. Module as in claim 4, characterized in that a shallow depression (15) as wide as the tensioning band (10) extends along the marginal section (13) of the lid (14), constituting an interlocking attachment for securing the tensioning band to the lid. 
     
     
       6. Module as in claim 5, characterized in that the marginal section (13) of the lid (14) can be hooked into brackets (19) on the base (2) of the housing (1) by means of sections (17) extending down beyond the location of the tensioning band (10) and of recesses (18) therein, constituting an interlocking attachment of the lid to the housing. 
     
     
       7. Module as in claim 6, characterized by the interlocking attachment constituted by the extending sections of the lid that are hooked into the brackets in conjunction with the connecting rods that extend along the groove-like depressions in the base and by force-application attachment constituted by the tensioning band.
